[0002] Agriculture is an important sector of the national economy. It is an industry that produces food and industrial raw materials by cultivating animal and plant products. Agriculture belongs to the primary industry. With the development of science and technology, manual sowing has been gradually replaced by seeding machines. Seeding machines are planting machines that use crop seeds as the objects to be sown.

[0003] In the prior art, patent CN115777288A discloses a crop seeder, including a frame and a support cylinder. A cylinder is fixedly installed at the top of the frame, and the output end of the cylinder penetrates through the top wall of the frame. A connecting seat is fixedly installed at the output end of the cylinder, and a pressure column is fixedly connected to the bottom end of the connecting seat. The pressure column is inserted into the support cylinder, and the pressure column and the support cylinder slide together. A spring is fixedly connected to the bottom end of the connecting seat, and the bottom end of the spring is fixedly connected to the bottom wall of the support cylinder. A support column is fixedly installed at the bottom end of the support cylinder, and a pressure head is provided at the bottom end of the support column. Both the support column and the pressure head are hollow, and the inner cavity of the support column is connected to the inner cavity of the pressure head. This invention, through the extension and retraction of the cylinder output end, can simultaneously insert the pressure head into the soil, open the two sealing plates, and input seeds into the pressure head. The overall synchronization is good, it is not easy to miss seeds, and it is convenient to operate.

[0004] While this device effectively solves the problems mentioned in the background technology, it also has the drawback that it requires manual pushing after each sowing. This results in uneven sowing spacing and the manual pushing can lead to sowing spacing that is too small or too large. If the sowing spacing is too small, it will affect the absorption of nutrients between seeds and the growth of crops. If the sowing spacing is too large, it will waste land and the manual pushing of the device is also quite laborious. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Please see Figure 1 - Figure 6 A crop sowing device includes a frame 1, with a motor wheel 101 movably connected to the inner wall of the frame 1 facing each other. The axle of the motor wheel 101 is connected through the frame 1. The axle of the motor wheel 101 is movably connected to a one-way rotation device 2, which is located on the side of the frame 1 away from the motor wheel 101. The one-way rotation device 2 includes a housing 201, and a uniform feeding device 3 is rotatably connected to the housing 201 via a belt. The uniform feeding device 3 is fixedly installed at the top of the frame 1. A harrow 102 is fixedly installed at the bottom of the frame 1. A brake device 4 is fixedly installed at the top of the frame 1, and the brake device 4 works in conjunction with the motor wheel 101. A soil covering device 104 is fixedly installed at the bottom of the frame 1, and a battery 105 is fixedly installed at the top of the frame 1.

[0025] The battery 105 is electrically connected to the motor wheel 101. A one-way rotation device 2 is provided so that when the motor wheel 101 rotates in one direction, it can drive the impeller 302 to rotate. When the motor wheel 101 rotates in the opposite direction, it cannot drive the impeller 302 to rotate. A uniform feeding device 3 is provided so that the seeds can be evenly sown on the land. A braking device 4 is provided to prevent the motor wheel 101 from spinning idly and causing the seeds to be mis-sown. The harrow 102 is used to dig furrows on the ground. The soil covering device 104 is used to push the soil on both sides of the furrows dug by the harrow 102 back into the furrows to cover the seeds. This device is suitable for dry land with relatively loose soil, but not suitable for wet land with relatively compacted soil. If the soil is too compacted, directly covering the seeds is not conducive to the growth of the seeds.

[0026] Specifically, the outer shell 201 is a hollow cylinder, which is nested on the shaft of the motor wheel 101. Several fixing seats 202 are fixedly installed on the inner wall of the outer shell 201. A circular hole is opened through one side of the fixing seat 202. A one-way pawl 203 is movably connected to the fixing seat 202 through the circular hole. A ratchet pawl 103 that cooperates with the one-way pawl 203 is fixedly installed on the shaft of the motor wheel 101.

[0027] The shorter end of the one-way pawl 203 rests against the inner wall of the outer casing 201. When the one-way pawl 203 is vertically above the motor wheel 101, the longer end of the one-way pawl 203 naturally falls due to gravity. When the motor wheel 101 rotates clockwise, it will drive the pawl 103 to rotate clockwise. The clockwise rotation of the pawl 103 will cause the longer end of the one-way pawl 203 to rotate. At this time, the outer casing 201 will not rotate. When the pawl 103 rotates counterclockwise, it will cause the longer end of the one-way pawl 203 to rotate. At this time, the shorter end of the one-way pawl 203 rests against the inner wall of the outer casing 201. At this time, the counterclockwise rotation of the pawl 103 will cause the outer casing 201 to rotate counterclockwise.

[0028] Specifically, the uniform feeding device 3 includes a mounting base 301, which is fixedly installed on the top of the frame 1. A cylindrical groove is opened inside the mounting base 301, and an impeller 302 is movably connected to the mounting base 301 through the cylindrical groove. The rotating shafts on both sides of the impeller 302 are connected through the mounting base 301. Feeding ports are opened through the bottom and top of the mounting base 301. A feeding hopper 303 is fixedly installed on the top of the mounting base 301. A feeding baffle 304 is connected through the side of the mounting base 301 away from the motor wheel 101. The impeller 302 has multiple blades, and a V-shaped receiving groove is formed between every two blades of the impeller 302. There are 18 V-shaped receiving grooves in total. Wedges 305 are movably connected between the blades of the impeller 302. Up to 15 wedges 305 can be placed. A pulley 306 is fixedly connected to one side of the impeller 302. The pulley 306 is movably connected to the outer casing 201 through a belt.

[0029] The counterclockwise rotation of the motor wheel 101 drives the pawl 103 and the outer casing 201 to rotate counterclockwise. The counterclockwise rotation of the outer casing 201 drives the belt to rotate counterclockwise. The counterclockwise rotation of the belt drives the pulley 306 and the impeller 302 to rotate counterclockwise. Seeds are placed in the hopper 303. The discharge baffle 304 controls the size of the discharge port at the top of the mounting base 301. When the impeller 302 rotates, the seeds will fall into the V-shaped receiving groove of the impeller 302 through the discharge port at the top of the mounting base 301. When the V-shaped receiving groove of the impeller 302 is vertically downward, the seeds will fall to the ground through the discharge port at the bottom of the mounting base 301. The number of V-shaped receiving grooves of the impeller 302 can be controlled by setting the wedge block 305, which facilitates the adjustment of the plant spacing.

[0030] Specifically, the braking device 4 includes a round shaft 401, which is fixedly installed on the top of the frame 1. A Z-shaped brake block 402 is rotatably connected to the round shaft 401. A spring 403 is movably connected to the side of the Z-shaped brake block 402 away from the motor wheel 101. A baffle 404 is fixedly connected to the spring 403. The baffle 404 is fixedly installed on the top of the frame 1. A rectangular groove is opened through one side of the baffle 404. One end of the Z-shaped brake block 402 can move within the rectangular groove of the baffle 404. A cable guide plate 405 is fixedly installed on the top of the frame 1. The cable guide plate 405 is located on the side of the baffle 404 away from the spring 403. A limiting hole is opened through the center of the cable guide plate 405. A handlebar 406 is movably installed on the handlebar of the frame 1. The handlebar 406 is fixedly connected to the end of the Z-shaped brake block 402 away from the motor wheel 101 by a steel wire rope. The steel wire rope should pass around the side of the cable guide plate 405 away from the baffle 404 and pass through the limiting hole in the center of the cable guide plate 405.

[0031] The side of the motor wheel 101 that contacts the ground has multiple grooves. The Z-shaped brake block 402 can rotate around the circular shaft 401. Under normal circumstances, the spring 403 will press against the end of the Z-shaped brake block 402 away from the motor wheel 101, so that the other end of the Z-shaped brake block 402 will not touch the motor wheel 101. When the handle 406 is squeezed, the handle 406 will pull the steel wire rope, so that the end of the Z-shaped brake block 402 away from the motor wheel 101 will approach the baffle 404, while the other end of the Z-shaped brake block 402 will press against the groove on the surface of the motor wheel 101, so that the motor wheel 101 cannot rotate. By setting the brake device 4, the motor wheel 101 can be prevented from spinning freely, thereby preventing the phenomenon of mis-sowing of seeds.

[0032] The working principle of this utility model is as follows: When in use, seeds are poured into the hopper 303. When the motor wheel 101 travels forward on the ground, the forward rotation of the motor wheel 101 drives the pawl 103 to rotate forward. The forward rotation of the pawl 103 drives the outer casing 201 to rotate forward. The forward rotation of the outer casing 201 drives the belt and pulley 306 to rotate forward. The rotation of the pulley 306 drives the impeller 302 to rotate. When the impeller 302 rotates, it will drive the seeds to be discharged through the discharge port at the bottom of the mounting base 301. By setting a brake device 4, when the device is turned or the motor wheel 101 slips, the phenomenon of mis-sowing of seeds will be prevented. By setting a one-way rotation device 2, when it is necessary to move the device backward, the rotation of the motor wheel 101 will not drive the impeller 302 to rotate, thus reducing the phenomenon of mis-sowing of seeds.
